Neijing Tu

Neijing Tu or Neijing Map was the earliest pictorial description of the concept and teaching of Xiuzhen of Taoism, dating from the Huangdi Neijing authored by the Yellow Emperor. Laozi in his Neixiu Jing also referred to this map. All of the principal aspects of practicing Jing Qi Shen, Neidan are visualized in this map

The map was complemented by a second anatomical version called the Xiuzhen Tu修真圖) or Xiuzhen Map. One of the Taoism scholars attempted to make a précis of this map.
